A student analyzed a viral genome and found that the genome had the following nucleotide composition.
lapo4ka [179]

Answer:

Option A) Double-stranded DNA

Explanation:

Note that the presence of thymine, a pyrimidine nitrogenous base in the genome indicates the presence of DNA.

Then, the summation of 28% adenine + 20% thymine + 35% cytosine + 17% guanine to yield 100% confirms that the DNA is double-stranded.

Thus, the structure of the viral genome is Double-stranded DNA.

  4. For the first time Night Blooming Jasmine will bloom and spread it's fragrance for 24 hours.
  5. Often when the earth revolves around its axis, a certain part of it receives light from the sun.But for the first time the earth will rotate around its axis without the sunlight falling on any part.
  6. people who are not allowed to go out of the house at night time can now enjoy the night out in the day too.
  7. Those trees and plants who slept in the hope that they would cook food in the morning with sunlight, they would not even know that their food has gone missing.
